<h3>Problems when running Database/Spana?</h3>

<p>What to do if you try the &ldquo;Chemical Equilibrium Diagrams&rdquo; sofware and things
do not work?</p>

<p>There are two kinds of possible problems:
<ul>
<li>The programs run but the results seem wrong:
<ul>
<li>Parts of the diagram are missing: <a href="SP_Failures.htm">the calculations failed</a></li>
<li><a href="SP_Strange_Results.htm">The diagram is strange</a></li>
<li>The equilibrium constants obtained from DATABASE are wrong:
  <a href="DB_Databases.htm">Modify the database</a></li>
</ul>
</li>
<li>You can not run a program. A message appears (or not) and the program
  is terminated abruptly. These type of problems are discussed below.</li>
</ul>
</p>

<h4>If the programs do not run:</h4>

<p>Some problems might be programming errors. Please send these observations
to the <a href="1_Acknowledgements.htm">author</a> at:

</p>
                                                    
<p>Because Spana calls background programs to make the calculations and to
handle diagrams, there is always the possibility that these Fortran programs do not
work in your special system. 
The Fortran programs have not been tested under all versions of Windows,
nor for example for Chinese or other non-Latin languages.</p>

<p>To find out the source of a problem:</p>
<ul>
<li>Open in Spana the menu <nobr>&#147;Preferences /</nobr>
General options&#148; and select
  &#147;<i>advanced</i>&#148; program level.</li>
<li>Then select &#147;<i>Keep windows open after calculations</i>&#148;. This will
  keep the calculation windows (for <a href="SP_SED.htm">SED</a>,
  <a href="SP_PREDOM.htm">Predom</a>,
  <nobr><a href="SP_PDF.htm">Plot-PDF</a>,</nobr> etc) open after
  calculations. Any error messages reported in these windows will give
  a clue on how to solve the problem.</li>
</ul>
